4 Claims. ((31. 98-2) This invention relates to improvements in of the same and illustrating the application of the motor vehicle and windshield warming devices device. and constitutes a division of my pending applica- Referring now more particularly to the drawtion, Serial No. 523,872, filed March 19th, 1931. ing wherein like numerals of reference indicate The primary object of the present device is to corresponding parts throughout the several 60 provide an improved means for controlling the views, the numeral 1 indicates generally the dedistribution of air which has been heated for introvice embodying the present invention, with which duction into a motor vehicle by a warm air heating are connected the warm air distributing nozzle unit of standard make, the device being designed 2 which forms the subject-matter of the parent in particularly for application to types of commercial application, as previously stated, and the con- 65 heaters of which those known as the Ha-Dees or necting pipe 3 which conveys the warmed air the Tropic Air are examples. from the collector unit 1 to the nozzle 2.

The heaters of the type referred to are usually ()nly those portions of the motor vehicle body mounted within the motor vehicle upon the dashwith which the present device and the distributboard behind the instrument board and the ing nozzle are connected, are illustrated and 70 heated air generated thereby is discharged dithese constitute the dashboard 4, the rear porrectly into the motor vehicle. The device emtion of the hood 5, the instrument dash 6, and bodying the present invention comprises a unit the windshield '7. adapted to position over the air discharge open- The numeral 8 indicates generally a warm air ing of the heater and having two outlets which are heat r f h typ pr vi usly referred to, which 75 controlled by a suitable valve, one of which outis mounted upon the dash 4 within the vehicle lets opens directly into the vehicle, while the other and which has a head 9, the face of which is is designed-to have a warm air conducting tube open to permit t e heated to cape into connected therewith for conveying the warmed the vehicle.

The device 1 is applied to the heater 8 in the manner illustrated in Figure 1 so that the flanges 11 will engage around the head 9 of the heater and the inner surface of the plate 10 will be brought-into close proximity to the warm air outlet face of the heater. It will be readily apparent from the description that by turning the disk 14 which operates in the nature of a valve, the entire opening 12 may be uncovered so that all of the air from the heater 8 will be discharged directly into the vehicle, at which time the outlet leading to the nipple 20 will be covered. By giving the disk 14 a quarter revolution from either the opened or closed position, one half of the opening 15 may be brought into position before the inner side of the hood 18 so that some of the warm air will escape through the nipple 20 and be conducted to the windshield. The other half of the opening 15 will permit the air to pass from the heater 8 into the vehicle. By turning the disk 14 half a revolution from its opened position, the outlet 12 can be completely closed so that only the hood 18 will receive warm air from the heater.

From the foregoing it will be readily apparent that with a device embodying the present invention, means is had whereby some of the air from the heater may be readily conducted to a suitable distributing head or nozzle mounted upon the windshield so that the latter may be. kept in a warmed condition during freezing weather and the formation of ice upon the windshield prevented.

Having thus described the invention, what is claimed is:-

1. In an attachment for an automobile having an air heater therein, a shield member designed to be secured to said heater and to obstruct the discharge of warm air therefrom, said shield having a pair of openings therein, a nozzle carried by the shield and overlying an opening for the connection of a tube to the shield for the conduction of warm air to a point of dis- 1 tribution, and a disk member rotatably mounted on the shield and having an opening, said disk overlying the shield openings and the end of the nozzle opening therethrough, and facilitating the selective discharging of warm air through the shield openings.

2. In an attachment for an automobile having an air warming device therein, a shield member comprising a flat plate having an angularly directed surrounding flange, said flange being designed to receive and frictionally engage the air warming device to maintain said shield in position over a face thereof from which warm air is discharged, said shield having a pair of openings therethrough, a hood overlying one ofsaid openings, a nozzle extending from said hood and adapted to have an air hose connected therewith to facilitate the conduction of warm air to a point remote from the shield, a disk ro'tatably mounted against the inner face of the shield to overlie said openings, said disk having an opening therein designed to be selectively registered with the openings of the shield, and means for facilitating the rotation of the disk from the front of the shield.

3. In an attachment for an automobile having an air warming device therein, a shield member comprising a flat plate having an angularly directed surrounding flange, said flange being designed to receive and frictionally engage the air warming device to maintain said shield in position over a face thereof from which warm air is discharged, said shield-having a pair of openings therethrough, a hood overlying one of said openings, a nozzle extending from said hood and adapted to have an air hose connected therewith to facilitate the conduction of warm air to a point remote from the shield, a disk disposed against the inner face of said shield, pivot means securing the radial center of the disk to said shield, means carried by the shield and engaging the edge of the disk to retain the same in position, said disk overlying the openings through the shield and having an opening designed to be brought into registry with either of the shield openings, and means carried by the disk and extending through and movable in one of the shield openings to facilitate rotation of the disk.

4. An attachment for an automobile air warming device of the type having a casing disposed within the automobile and having a warm air discharge face, comprising a flat body designed to overlie said face, a flange carried by and surrounding said flat body and adapted to receive the casing to retain the flat body in position thereover, said flat body being formed for the passage of air therethrough, means carried by the fiat body for facilitating the attachment of a warm air conducting pipe thereto for the reception of a portion of the warmed air passed therethrough, a portion of the warmed air passed by the flat body entering directly into the automobile, and a valve disk pivotally secured to the flat body to rotate in a plane paralleling the plane of the body and having an aperture whereby the passage of warm air through the body directly into the automobile or to said pipe may be selectively controlled.
